Whenever the city engineer finds any non-permitted, prohibited substance discharge or any other material of any kind, in or upon the sidewalk abutting or adjoining any parcel of land, or upon any parcel of land or grounds, which may result in an increase in pollutants entering the city storm drain system, the city engineer may give notice to remove any non-permitted, non-prohibited substance discharge that the city may provide. The industrial/ commercial discharger who receives such a notice shall undertake the remediation activities as described in the notice. (Ord. 229 § 3, 2005)
